- COMBINED HEATER. AND VI'ENTILATOR.

To all whom it concern Be it known that I, ROBERT G. BOONE, a at sbiiry Park, in the county of Monmouth and :State of New Jersey, have invented newv and useful Improvements in Combined Heaters and Ventilators, of which the following is a specification. I I w v This invention relates to a combined heater and Ventilator and has for its primary object the provision of means for heating a" current of air electrically and for drawing the heavier or cool air by induced suction into the presence of a heating unit so that the air will rise in a room and be heated in proper ratio to its velocity; and

loss of weight through its assimilation of heat from said unit, the device serving to establish atmospheric rotation of the air in a manner which will enable the device to be i used economically while heating the air to the .desired temperature. Another object of the invention is to provide a device of the character described which will be of portable construction and capable of being connected in any well known source of electrical current.

A still further object of the invention is to provide a device of this character which will include a combination of elements which can be operated singly or together so that the device can be used either as aheater or asa means for cooling and {disturbing air and for discharging the same into a room to be ventilated.

Another object pf the invention is to provide a de vice of this characterawhich is capableof being connected with an outside air duct or source so thatfresh atmospheric air may be taken into the device and then subjected .to the action of a heating means andthen finallythrown off into the space tobe heatedand ventilated.

A still further object-of the invention is to provide a combined heater and ventilator which will include a heating unit, an air impelling' and' suction unit, and means associated respectively with both of said units for causing full impingement'of the air to a be heated against 'the heating unit and for I accelerating the discharge of the heated air after it'has'passed said heating unit.

With the above and other'objects in view which will appear as'the nature of the inventionis better understood, the same. consists in the improved construction andnovel Specification of Letters Patent.

. after bei fully arrangements of the invention, it being, however, under stood that no limitations are necessarily made to the precise structural details [therein exhibited-but that changes, alterations and modifications within the scope of the claims may be resorted to when desired. F gure l is a vertical section through the device.

particularly i with a shoulder 6 and 'annular' flange 7. M

"Rising from the base with, its lower end surrounded by the-flange 7 is a drum 8 and seated on the shoulder 6' and extending across the bottom of the drum is a plate or suitable support 9 having perforations 10 there1n for a purpose to be hereinafter explained. Within the drum 8 is a shell- 11 whose walls are spaced from the walls of the drum so as to provide an intervening air duct 12 between the mentioned parts. This shell is preferably of less length than the drum 8v so that the bottom,

of the shell is spaced from the plate 9 to establish communication between the duct I 12 and the bore orpassage-Way 13 of said shell. A grilled top plate or grate 1 1 extends over the upper ends of the drum -8 'and said inner shell 11, the perforations 1 5 therein.functio11ing for the egress of air from the device and the perforations 16 functioning for the ingress of air to the -duct 12 so that a continuous strata of out side air will be maintained in said duct 12 v to cool the-drum 8, the spacingof the base of the shell 11 from the support 9 serving to permit the air as it is drawn downward through the duct to finally enter the pas"- sage-way 13; of th innershell fora purpose-to be hereina er explained.

Located in the passageway 13 and supported therein by brackets 17 which. are secured to the inner shell 11 is a heatingunit w "18, This unit is of perforatedfrusto conical formation and is hollowr It is formed pref- -teria-lf such as oroelain. An electric cir- .-c.ui t is indicate at 19 and included in said .erably of insulating or heat resisting ma- K r circuit and suitably associated with the porcelain cone is -'a resistance wire 20 which is wound preferably onto said cone. In said circuit is also arranged anelectric motor which is conventionally illustrated at 21, the same mounted upon the plate 9 and disposed beneath the large end of the porcelain cone. The motor isprovided with a fan 22 whose blades are set so as to draw the cold air upward from the base of the structure or floor line as the case may be and then cause said air to be impelled upward through the bore of the porcelain cone and around the same. This "causes the cold air to impinge against the cone to be thoroughly heated electrically through the arrangement previously referred to. The fan further serves to cause the air thus heated to be discharged by way of the perforations 15 into a room to be heated.

On the inside of the porcelain cone is a baflie member which is somewhat of the double spear. shaped formation, the pointed ends 23 and 24 of which are reversely extended and connected together by a neck portion 25 which preferably increases in width in the direction of the large parts of said pointed ends so as to merge thereinto. The restricted end of the point 24 is proje;ted toward the fan 22 so that the air is thrown outward and radially against the inner'walls of the hollow cone, the neck 25 and upper point 23 of said bafile mutually serving to cause the air to be deflected and thoroughly subjected to the action of the resistance wire 20. A second baffle member 26 is arranged outside of the hollow cone and the same is curved upward and inwardly in the direction of the walls of the cone so that the air which passes outside of the cone or between it and the shell 11 will be thrown into impingement with the cone to be thorou hly heated.

' switch 27 in the electric circuit 19 func-' tions to permit the air heating unit to be shut off or cut out of the circuit when the fan 22 is desired for use as a ventilator. A rheostat 28 is also located in the circuit so that varying amounts of current can be taken into the resistance wire 20 according to the amount of heat desired.

The structure is portable and is capable of being placed at any point or place where the heater or ventilator. is desired. It may be mounted upon the floor of a room so that air may be drawn into the structure directly 'from the-floor line and than impelled by the action of the fan 22 against the heating unit when the device is used as a heater. The same operation of drawing the air into the structure and discharging the samethere from is also true when the device is used simply as a ventilator for disturbing or churning atmospheric air. The base of the structure may, if desired, be connected with.

the co umn so as to provide a heat insulat-.

ing chamber between the respective walls, a heating element in' said shell, and means for drawing cold air into the shell and for subjecting said air to the action of the heating element and for subsequently discharging the heated air from the shell, said means serving to produce a down draft in the space between the walls of the shell and the walls of the column, as and for the purpose specified. I

2. A structure of the class described comprising, a hollow open ended column, a concentric shell associated with the column and having its walls spaced from the walls of the column so as to provide aheat insulating chamber between the respective walls, a heating element in said shell, and means for drawing cold air into the shell and for subjecting said air to the action of the heating element and for subsequently discharging the heated air from the shell, said means serving to produce a down draft in the space between the walls of the shell and the'walls of the column, and mechanism for actuating said means and for controlling said heating element collectively or singly, said means servin to'draw the atmospheric air into the space etween the walls of .said member by induced suction.

In testimony whereof I have afiixed my signature. I
